Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
The new points switch machine and installation device are all made up of box-shaped parts, and the main machine of the point switch machine is firstly installed, and at the same time the locking device is assembled, then connected and fastened with steel rail, and then the driving rod members (action rod, connecting rod and locking rod) and indication rod are installed. The parameters of the new turnout switch machine (including four parameters of a sealing parameter, a gap parameter of an indication rod, an opening parameter and an opening adjustment parameter of a tie rod) need to be adjusted, the turnout has positioning and inversion, namely 8 values need to be adjusted, the 8 values also influence each other, the respective error range needs to be met, the limitation does not exist, 4-6 persons are needed to cooperate, and the adjustment time cannot be determined. Therefore, the existing switch machine takes longer time for replacement and installation, and the construction cost is higher.
Therefore, referring to fig. 1, the embodiment provides a construction method for presetting signal turnout in-situ replacement parameters, which can effectively reduce the time for replacement and installation, thereby reducing the construction cost. Specifically, the construction method for presetting the signal turnout in-situ replacement parameters in the embodiment specifically comprises the following steps:
s101: measuring original parameters of an original turnout switch machine to be replaced; the original parameters comprise a close contact parameter, a rod gap representing parameter, an opening parameter and a sharp rod opening adjusting parameter; comparing the original parameters of the original turnout switch machine with a standard value range, and if the original parameters do not reach the standard value range, adjusting the original turnout switch machine to enable the original parameters to be in the standard value range; the standard value range is +/-5 mm;
s102: pre-adjusting parameters of a replacement turnout switch machine which needs to replace the original turnout switch machine according to the measured original parameters so that the difference value of the parameters of the replacement turnout switch machine and the original parameters of the original turnout switch machine is within a preset adjustment precision range;
s103: and (4) dismantling the original turnout switch machine, and installing the preset replacement turnout switch machine at the position of the original turnout switch machine.
That is to say, this disclosed signal switch normal position reloads parameter preset construction method, before changing original switch machine, earlier through measuring the parameter of the original switch machine that needs to be changed, to prepare the parameter of the replacement switch machine of replacement and carry out the preset, make it unanimous with the parameter of original switch machine to this reaches new switch and assembles the back of accomplishing, and the switch fine-tuning parameter satisfies the precision standard, and can shorten the construction duration to a certain extent through the preset, thereby can reduce construction cost. Particularly, after the parameters are pre-adjusted, the problem that the turnout is long in time consumption in fine adjustment is solved, the construction time is shortened, the efficiency is improved, and the construction cost is reduced. In addition, the measurement of the switch parameter replacement and the pre-adjustment of the newly installed switch parameter can be carried out at any time before construction, and the cost is low. The time of the skylight is saved by fine adjustment of the turnout parameters, and the investment of constructors can be reduced by utilizing the installation stage; meanwhile, the short construction time means that the influence of the skylight sealing on railway running and transportation is small, and the running benefit is created
Before specific construction, a construction preparation operation may be performed first. The concrete construction preparation operation is as follows: firstly, reporting a skylight construction plan three days in advance according to the construction requirements of a railway bureau business line. Then, the main staff of the business line construction: and the construction responsible person, the communication staff of the standing station and the protection staff obtain the construction qualification certificate of the business line. Secondly, the inspection of newly-installed turnout fittings is complete and complete, and the checking of the newly-installed turnout model is consistent with the replacement turnout model. And finally, compiling a turnout parameter checking and testing table, and auditing and approving by technical responsible personnel of the department of project.
During specific construction, in step S102, the step of pre-adjusting the parameters of the replacement switch machine that needs to replace the original switch machine according to the measured original parameters includes:
s1021: assembling to form a replacement turnout switch machine;
s1022: and pre-adjusting according to the original parameters and the parameters of the replacement turnout switch machine.
Specifically, in step S1021, the step of assembling the replacement switch machine may include: pre-assembling the outer locking frame connecting rod at a preset position, and installing limiting iron, wherein the limiting iron is locked without being inserted into a groove; connecting and injecting the main engine oil pipe and the auxiliary engine oil pipe of the replacement turnout switch machine, and exhausting air in the oil pump.
Then, the original turnout switch machine is detached, and when a replacement turnout switch machine is installed, the sealing parameter (a), the indicating rod notch parameter (b) and the opening parameter (c) of the replacement turnout switch machine are hidden to the replacement turnout switch machine through a sealing adjusting sheet, an opening adjusting sheet and the number of teeth.
Next, the close contact parameter (a), the indication rod notch parameter (b), the stroke parameter (c), the tie rod stroke adjustment parameter (d), and the like are set at the new turnout, and the technician enters the next process after rechecking and confirming.
And replacing the turnout switch machine by the electric operator to a positioning state and a reverse state, checking notch parameters and turnout switch rail opening range in the host, and finishing fine adjustment if the turnout switch machine is within a standard allowable range. The practice test shows that the fine adjustment of the turnout can reach the standard allowable value once by adopting a parameter pre-adjusting method, and only fine adjustment is needed according to the requirements of equipment management units.
And finally, putting the train into operation after the in-situ reloading is in place and the construction is completed and started, wherein the equipment management unit closes the last pass, rechecks the fine adjustment parameters and the control circuit, and agrees to sell and release the train after the recheck is qualified. The construction unit inspects the road materials, and the construction responsible personnel inspects the road materials, and after the cleaning of the road materials is finished, all personnel and tools go off the net.
In addition, before the step of removing the original switch machine and installing the pre-adjusted replacement switch machine at the position of the original switch machine, the method further comprises the following steps:
and (4) blocking the line for installing the original turnout switch machine.
During the specific construction, after step S102, that is, after the step of performing the pre-adjustment according to the original parameters and the parameters of the replacement switch machine, the method further includes:
and testing the pre-adjusted parameters of the replacement turnout switch machine so that the difference value between the parameters of the replacement turnout switch machine and the original parameters of the original turnout switch machine is within the preset adjustment precision range. For example, the parameters of the replacement switch machine may be adjusted to be consistent with the original parameters of the original switch machine, so that the original switch machine may be subsequently replaced by replacing the switch machine.
During the concrete construction, after the step of measuring the original parameters of the original switch machine to be replaced, and before the step of pre-adjusting the parameters of the replacement switch machine to replace the original switch machine according to the measured original parameters, the method further comprises the following steps:
and comparing the original parameters of the original turnout switch machine with the standard value range, and if the original parameters do not reach the standard value range, adjusting the original parameters to enable the original parameters to be in the standard value range. For example, if the range of the first traction point is 160 ± 5mm, and the range of the existing switch is 155mm or 165mm, which is close to the overrun value of the standard value range, the original switch machine needs to be adjusted first.
In the specific implementation, the sealing parameter (a) is the accumulated thickness of the sealing adjustment sheet at the position of the locking frame. The thickness of the seal adjustment sheet at the turnout locking frame is generally 0.5mm, 1mm and 3mm, the seal parameters are the combination of the adjustment sheets of all the sizes, and the accumulated thickness a of the switch seal adjustment sheet is recorded; the sealing adjustment sheet is positioned and reversed by a parameter a1 and a2 respectively, and the sealing parameters of the replacement turnout switch machine are consistent with the sealing parameters of the original turnout switch machine by adjusting a1 and a 2.
It should be explained that the locking frame is used to ensure that the motor, the transmission rod and the point rail close contact rod are on the same vertical plane, so that the point rail close contact rod does not move in a dislocation way due to temperature change, which affects normal use. And the contact adjustment sheet is used for realizing the contact between the stock rail and the switch rail of the turnout.
According to one embodiment of the present disclosure, the rod notch parameter (b) is a distance representing a distance of the rod adjustment nut from a top end of the rod piece. During specific implementation, the distance from the turnout indication rod adjusting nut to the top end of the rod piece, namely the exposed screw thread length b, is measured through a measuring tape; based on the orientation and flip states, the two sides measure orientation b1 and flip b2, respectively. The indication rod gap parameters of the replacement switch machine are consistent with the indication rod gap parameters of the original switch machine by adjusting b1 and b 2.
It should be explained that the indication rod is a switch indication rod, one end of which is connected with the indication rod of the switch machine and the other end is connected with the switch tongue, and the indication rod is used for checking whether the tongue is closely attached to the stock rail or not and determining whether the switch is positioned or reversed through the extending length when acting with the switch.
In addition, the gap parameter of the indicating rod is adjusted to keep the installation parameter values of the new indicating rod and the old indicating rod consistent, so that the replacement turnout switch machine cannot be locked (operated to a positioning position or a reverse position) due to too large or too small gap value of the detection rod in the replacement turnout switch machine in the action process, the turnout cannot be operated in place, the route cannot be normally arranged, and further the train operation is influenced.
According to one embodiment of the present disclosure, the opening parameter (c) is the number of opening adjustment tabs at the lock frame. In a specific implementation, the thickness of the adjusting sheet at the U-shaped lock frame is generally 2mm, and the number c of the used adjusting sheets is recorded; the trip tabs are positioned and inverted by a parameter c1, c2, respectively. The newly installed turnout generally does not suggest adding an adjusting sheet at the U-shaped lock frame, but the turnout is changed in situ to be consistent with the parameters in use, so the turnout needs to be added. And c1 and c2 are adjusted to make the opening range parameter of the replacement turnout switch machine consistent with the opening range parameter of the original turnout switch machine.
It should be noted that the stroke parameter (c) is also called a stroke parameter, which is a stroke distance that the switch machine pulls the switch rail and the stock rail closely after the opening values of the switch rail and the stock rail at the switch rail traction point meet the design requirements. The uneven opening can lead the fixed and reverse travel of the indicating rod to be uneven, lead the turnout to lose the indication and be incapable of being arranged into a route.
According to one embodiment of the present disclosure, the toe rod reach adjustment parameter (d) is the number of closed teeth at the point iron coupling teeth of the switch.
